Mixed Signals

Hi. So I've been talking to this boy for about two weeks now, and he's been giving me a lot of mixed signals. 
So we've hung out about five times since we started talking and we even kissed the last time we hung out. But the weekend and the week after we kissed he ignored me and only called me on Monday after we hung out on the Tuesday before.
He already asked me on a date before but then had to "un-ask" me because of issues with friends and he said he doesn't wanna lead me on but he's continued to flirt with me and say the stuff that he promised he wouldn't say anymore.
After we kissed I had to ask him if he also had a crush on me and he denied it and he told he doesn't wanna lead me on again. But he didn't make it convincing, like he said it and I didn't believe him at all.
I just don't really know what to do because he shows all the signs of having a crush on me and he's even kissed me yet he goes 6 days of not talking to me and doesn't want to admit anything and I just don't really understand it.
I guess I'm just hoping somebody has some advice about  what's going on with him or what I should do. Please someone help me and thanks in advance if you do.
